I tried to install device Win7 drivers from HP Probook 450 list and below are the drivers compatible with my TouchSmart 14 Sleekbook:
wireless network - Qualcomm Atheros AR9000x 802.11b/g/n wireless wifi
ethernet - Realtek ethernet controller, and
audio - IDT High Definition (HD) Audio Drivers
usb 3.0 -USB 3.0 drivers
These should give me enough to start working. Please let me know if there are other more compatible drivers for video/display, camera, and etc. The chipset driver provided from the original Win8 selection works with Win7 which provided many good default stand-in for now.
Thanks again for your help!
